Life-history evolution in the orange-tailed skink populations living in different climates.

The life-history traits of ectothermic animals can be influenced by many abiotic factors, including climate. As an ectothermic species, we questioned whether the life-history characteristics of the orange-tailed skink (Eumeces schneiderii) populations differ between two different environments/climates. Our findings showed that the average body size of lizards living in the Mediterranean climate zone was higher than those in the continental climate zone. However, although Mediterranean population had higher mean values regarding average age, there was no discernible difference between the two climate zone populations. When considering all populations collectively, it has been discovered that the species' maximum lifespan is 18 years. Body size notably increased with age in both populations. Through the utilization of the von Bertalanffy equation, the anticipated growth parameters portrayed a highly accurate connection between age and snout-vent length. In conclusion, lizards living in habitats characterized by milder Mediterranean climates were found to have larger body sizes than continental populations, but both populations were comparable in terms of mean age. This difference can be explained by several factors, including activation time, temperature, precipitation, food abundance, and the presence of predators.

Molecular Detection of Tacheng Tick Virus-1 (TcTV-1) and Jingmen Tick Virus in Ticks Collected from Wildlife and Livestock in Turkey: First Indication of TcTV-1 Beyond China.

Background: Jingmen tick virus (JMTV) and Tacheng tick virus-1 (TcTV-1) are emerging tick-borne viruses that have been recently confirmed to be etiological agents of human disease in China. However, the ecology of JMTV and TcTV-1, especially their association with ticks in wildlife and livestock, remains largely unknown in Turkey. Materials and Methods: Eight hundred thirty-two tick specimens in 117 pools were collected in Turkey between 2020 and 2022 from wildlife (Miniopterus schreibersii and Rhinolophus hipposideros; n = 10, 1.2%; Testudo graeca; n = 50, 6%) and livestock (Ovis aries and Capra aegagrus hircus; n = 772, 92.7%). The specimens were individually screened for JMTV and TcTV-1 using nRT-PCR assays targeting the partial genes. Results: JMTV was detected in one Ixodes simplex pool and two Rhipicephalus bursa pools collected from central and Aegean provinces, respectively. TcTV-1 was identified in five Hyalomma aegyptium pools collected in Mediterranean provinces. No coinfection was detected in the tick pools. Maximum likelihood analysis of JMTV partial segment 1 sequences reveal that these sequences form a separate cluster together with viruses previously characterized in Turkey and the Balkan Peninsula. The phylogenetic analysis of the TcTV-1 nucleocapsid sequences indicates that they are closely related to viruses in ticks, sheep, cattle, and humans in China, but form a separate group among themselves. Conclusion: This study provides the first molecular evidence of TcTV-1 in Hy. aegyptium in Turkey. In addion, these findings indicate that JMTV and TcTV-1 extend ticks species and geographic distributions. Thus, multiregional surveillance in livestock and wildlife is needed to evaluate potential tick vectors and the human health impact of these viruses in Turkey.

Multiple orthonairoviruses including Crimean-Congo hemorrhagic fever virus, Tamdy virus and the novel Meram virus in Anatolia.

We conducted orthonairovirus RNA screening of 7043 tick specimens-representing 16 species-collected from various regions of Anatolia. In 602 pools, Crimean-Congo hemorrhagic fever virus (CCHFV) Europe 1 and 2 lineages were detected in seven pools (1.1 %) comprising Hyalomma marginatum, Hyalomma scupense, Rhipicephalus bursa, Rhipicephalus sanguineus sensu lato and Rhipicephalus turanicus ticks. In pools of Hyalomma aegyptium, we detected Tamdy virus (TAMV) and an unclassified nairovirus sequence. Next-generation sequencing revealed complete coding regions of three CCHFV Europe 2 (AP92-like) viruses, TAMV and the novel orthonairovirus, tentatively named herein as Meram virus. We further performed in silico functional analysis of all available CCHFV Europe 2, TAMV, Meram and related virus genomes. The CCHFV Europe 2 viruses possessed several conserved motifs, including those with OTU-like cysteine protease activity. Probable recombinations were identified in L genome segments of CCHFV and TAMV. Through phylogeny reconstruction using individual genome segments, Meram virus emerged as a distinct virus among species within the Orthonairovirus genus. It further exhibited conserved motifs associated with RNA binding, encapsidation, signal peptidase cleavage, post-translational modification, RNA-dependent RNA polymerase and OTU-like activities. Bole tick virus 3 was also detected in two pools with CCHFV reactivity. Hereby, we describe a novel tick-associated orthonairovirus, in a CCHFV-endemic region with confirmed TAMV activity. Human and animal health impact of these viruses need to be addressed.

Importance of electromyography and the electrophysiological severity scale in forensic reports.

Forensic reports on traumatic peripheral nerve injuries include dysfunction degrees of extremities, which are arranged according to the Turkish Penalty Code. The aim of this study is to discuss the role and importance of electromyography while preparing forensic reports in the cases of traumatic peripheral nerve injuries and the usefulness of scoring systems. A modified global scale, recommended by Mondelli et al., was used to assess the electrophysiological impairment of each peripheral nerve. Forensic reports of 106 patients, reported between 2002 and 2004, were evaluated. Thirty-four percent of the cases were reported as "total loss of function," 41.5% were reported as "functional disability," and there were no dysfunctions in the other cases in forensic reports that were prepared based on Council of Social Insurance Regulations of Health Processes and Guide prepared by the Council of Forensic Medicine and profession associations of forensic medicine. When we rearranged these forensic reports based on the electrophysiological severity scale (ESS), it was clearly found that all of the score 2 cases and 86.7% of the score 3 cases corresponded to "functional disability" and 91.4% of the score 4 cases correspond to "total loss of function." We found a significant correlation between the ESS and functional evaluation in peripheral nerve injury cases. Evaluation of functional disabilities in peripheral nerve injuries with the ESS represents a standardized and objective method used for forensic reports.

Cranial optic nerve involvements in patients with severe COPD.

OBJECTIVE: The relationship between neuropathy and increased morbidity in patients with COPD is clear, but few studies have assessed cranial neuropathies, especially optic nerve involvement, in COPD patients. We evaluated peripheral involvement of the optic nerve and determined factors influencing this condition in patients with severe COPD. METHODOLOGY: Twenty-eight patients, mean age 59.4 +/- 9.4 years, diagnosed with severe stable COPD according to the GOLD criteria, and 20 age- and gender-matched healthy individuals, mean age 55.6 +/- 8.5 years, were included in the study. All subjects underwent visual evoked potential (VEP) assessment together with detailed clinical and laboratory examination to exclude concurrent risk factors for neuropathy. RESULTS: VEP assessment showed significant abnormalities in COPD patients (82.1%) (commonly amplitude abnormalities) when compared with healthy controls. CONCLUSIONS: The optic nerve is often involved in patients with severe COPD, possibly as part of a polyneuropathy, and this is related to acidosis, hypercarbia and airway obstruction, independent of disease duration, smoking and age. These results should be taken into consideration when determining management strategies for these patients.

Subtypes of carpal tunnel syndrome: median nerve F wave parameters.

The carpal tunnel syndrome (CTS) provides a model for analyzing the effects of focal nerve injury on F waves. We studied 127 patients (164 CTS) with clinical and electrophysiological CTS and 35 healthy controls in order to determine the alteration of F wave parameters in different types of CTS and to evaluate the most predictive F wave abnormality for each type. Minimal, maximal and mean F wave latencies, F wave persistence and chronodispersion recorded from abductor pollicis brevis (APB) muscle with wrist stimulation were compared. Twenty-three patients (29 CTS) had prominent demyelinating type CTS, 37 patients (45 CTS) had prominent axonal type CTS and 60 patients (90 CTS) slight demyelinating CTS according to electrophysiological parameters. The amplitude of APB muscle and F wave persistence were correlated significantly (R: 0.36, P<0.001). Minimal F wave latency was more prolonged in demyelinating group than in the axonal and slight demyelinating groups (P=0.001). In conclusion, F wave determination, as a simple and valuable method, allows the discrimination between demyelinating injury and axonal degeneration and increases the diagnostic yield in CTS.
